Abstract
The present invention relates to a multihead serial printer comprising a plurality of printing heads mounted on different carriages and having a high-speed printing mode in which a plurality of printing heads print different letters and a high-density printing mode in which a plurality of printing heads print different parts of one letter. These two printing modes can be changed over between each other.
